01 S&B Filters 75-5068 Cold Air Intake For 2013-2018 Dodge Ram Cummins 6.7L (Editor’s Choice)

Why it Stands Out to Us

With advanced airflow and high quality parts, the S&B Filters 75-5068 provides optimum efficiency and support to your engine. Since it’s been designed to avoid engine lights and avoid voiding your warranty upon installation, it’ll be highly convenient for users who don’t want to upgrade their vehicles but simply want to modify them and increase their performance.

What’s more, this cold air intake uses state-of-the-art technology to apply the most accurate amount of oil to your filter before delivery, which helps you make the most out of your kit. Though it’s a high-end option, the value you get out of the kit will be worth it in the long run.

03 aFe Power Magnum FORCE 51-11342-1 Dodge Diesel Trucks 03-09 L6-5.9/6.7L (Worth a Second Look)

Why it Stands Out to Us

With a 105% increase in airflow intake compared to the factory intake, the aFe cold air intake kit is truly a wonder to behold. Not only does it produce an extra 14 horsepower, but it also has an insulating plastic tube that resists the smoldering heat from your engine. The well-built quality parts work together in tandem to provide your engine with maximum oxygen supply to enhance combustion and increase performance.

04 Cold Air Intake Kit Oiled Filter Replacement for 2007.5-2012 Dodge Ram 6.7L Cummins Diesel (Easy Installation)

Why it Stands Out to Us

Due to all the parts being made of aluminum, the BetterCloud is phenomenal at resisting the high temperatures within your engine. This is a convenient feature as it prevents the cold air from becoming warm and having the opposite effect on your engine’s performance than intended. The handiest feature in this kit is its user-friendly installation process that even an amateur can do without external help. The entire assembly can be finished easily without any advanced tools either. The kit is also quite affordable compared to others on the market so anyone who wants to improve their engine’s mileage can surely opt for the BetterCloud.

Our Experience with the BetterCloud YJ8037

• This kit was easy to install, had great quality, and maximized efficiency.
• The best thing about the BetterCloud YJ8037 is its ease of installation. The process didn’t require any advanced tools and we could set up the whole thing pretty fast.

Even those who don’t have a lot of experience with machinery can easily set this up as the whole thing is as simple as can be.
• Another thing we enjoyed was the responsiveness of the engine. We’re sure that this added to our truck’s horsepower and improved fuel economy.

Best Cold Air Intake for 6.7 Cummins: Buying Guide

1. Airflow Design

Ensuring your engine gets proper airflow is vital as it will allow your 6.7 Cummins to get the burnable oxygen it requires. You’ll also need to be wary of air intake kits that mess with the filtration process of your engine. When you’re buying a kit, make sure that your unit can facilitate good filtration and sufficient airflow simultaneously in order to increase the longevity of your 6.7 Cummins.

2. Fitting & Performance

If you don’t get the right size air intake kit, you might end up choking your engine, which might result in greater damages in the long run. If you’re purchasing a kit online, make sure to match the kit’s specifications with the user manual provided with your vehicle to avoid any mismatches.

3. Inclusion of Necessary Parts

Ensure that your kit has all the required parts like the pipes, filters, and hoses. Having all the parts will make installation easy and keep your engine free of trouble.

4. Hose & Pipe Material

While the general consensus is that aluminum pipes have precedence over plastic ones, it is more accurate to say that the material doesn’t play a big part in ensuring effective air intake mechanisms.

5. Filter Type

a) Dry

Though dry ones are more commonly used, oil types are the best when it comes to increasing the lifespan of your filter.

b) Oil

Oil filters will ensure longevity, however, they are not recommended for some vehicles with sensors as the oil makes them more prone to damage.

6. Durability

The more layers your kit has, the better its performance and durability will be. The multiple layers protect the system from wearing out and will serve you for a long time.

7. Water resistance

If you want to maximize the power of your 6.7 Cummins engine by navigating through dangerous terrains and swamps, you’ll want to ensure your air filter system is water-resistant. Otherwise, water will enter your air intake kit and your engine will get damaged.

8. Price

Cold air intake kits can range from as low as $200 to up to around $1600. The wide range will allow you to opt for a kit that simultaneously serves your needs and isn’t a burden on your wallet.

Advantages of Investing in Cold Air Intakes

Avoiding Warranty Voiding

If you don’t want to replace your entire vehicle and void its warranty, you may want to install a cold air intake as it will do wonders for your engine and provide a solution to your engine problems. This way, you get to keep your warranty and also experience enhanced engine performance for a small price.

Increased Acceleration

Your vehicle’s responsiveness will increase due to the large amount of cold air being delivered to your engine by the cold air intake. It will be much easier to reach your desired speed because of the enhanced performance.

Increased Horsepower

As cold air burns fuel more efficiently than hot air due to faster oxygen combustion, a cold air intake kit may increase the horsepower of your vehicle. How much horsepower has been added depends completely on your vehicle configuration.

Improved Fuel Mileage

Internal combustion engines require adequate amounts of oxygen to burn fuel and produce power. Therefore, if there isn’t enough oxygen being supplied to the engine, it will use up more fuel. Installing a cold air intake improves fuel economy and horsepower and decreases your fuel consumption, saving you money and providing better performance in the long run.

Reduced Operating Cost

Since cold air intakes are equipped with air filters that need to be cleaned only after 15,000 to 40,000 miles, you would save a lot of money that would otherwise be spent on replacing the paper air filters that come with factory air intake systems. You can simply wash them with soap and water and you’d be good to go!

Types of Cold Air Intakes

RAM Air Intake

A long tube extracts the air from the high-pressure parts at the front. These intake kits sometimes have pre-filters at the front to protect the engine from splashes and dust.

Short RAM Unit

Since they have shorter air tubes, the distance from the filter to the engine gets reduced and this causes the air to not be as cool as true cold air intake units. However, this means that short RAM units can fit in the small spaces inside cramped engine compartments.

True Cold Air Intake

Due to having quite a long tube, it can extract cool air further away from the engine. This is advantageous for the engine as cooler air is denser and has a higher concentration of oxygen in it. This allows fuel to burn more easily and reduces fuel consumption over time.

FAQs:

1. Why is it necessary to supply cold air to the 6.7 Cummins engine?

Ans. This is to ensure your engine has maximum power and performance. Cold air facilitates more efficient combustion and reduces fuel consumption, saving you money in the long run. It also helps decrease the level of impurity in your engine and increases its lifespan.

2. Is an aftermarket cold air intake better than the Original Engine Manufacturer?

Ans. When you compare an aftermarket cold air intake kit to the OEM one, you’ll find that the former ensures more efficiency in your engine as it successfully redirects more oxygen for combustion.

3. How often should I clean my cold air intake units?

Ans. This depends on the area you’re located in. If you’re driving in a highly polluted area, you may need to clean your filter before it reaches 40,000 miles.

4. Will a replacement air intake system increase the level of engine noise?

Ans. If you’re using a low-quality air intake unit, it will be prone to heating up. This is counterintuitive as the purpose of the cold air intake is to reduce the temperature of the air in your engine. Invest in a high-quality kit to avoid this from happening.

5. How often should I replace my filters?

Ans.  If you live in an area with high pollution, you may want to replace the filters whenever you think you’re not getting the most efficiency. However, usually it is recommended that you change your filter anywhere between 15000 to 40000 miles.
